Sienna Miller looked gorgeous in Dolce & Gabbana florals last night as she joined James Franco to host the swanky launch of BMW's new electric car in London.
Hitting the event in a vintage-style sundress from the Italian design duo, the British beaut proceeded to nail dreamy summer prints.
The flirty frock flattered Sienna's already-amazing figure with classic fit and flare shaping as she played host to fellow VIPs including Poppy Delevingne and Laura Bailey.
Oh Sienna, you dreamboat.
Are you loving Sienna's floral prints as much as we are?
